i assume you meah exh temp. do you have any eng codes?
DID NOT HAVE ANY CODES WHEN I REMOVED THE PROGRAMMER AND YES THE EXHAUST TEMP.
poss restricted exh system, like plugged catt. what is the cooling system temp?
Engine temp is normal. It has 4" exhaust from the turbo out, seems to be flowing fine. How could i check that? The turbo doesn't make any abnormal noises and seems to run and pull fine, boost gauge shows about normal as always. Recently cleaned my k&n air filter changed fuel filter and engine oil after this started and no change
poss waste gate actuator. remove frt o2 sensors and adapt a pressure gauge to those whole and read exh back pressure. should be close to zero.
ok thanks i will have that checked and see if thats it. let everyone know in a few days what i find out
